Abstract (en)

[origin: EP2716747A1] Surfactant mixture comprises at least one anionic surfactant, and 10-90 wt.% of at least one nonionic surfactant (I). Surfactant mixture comprises at least one anionic surfactant, and 10-90 wt.% of at least one nonionic surfactant of formula (R1O-(G) p) (I). R1 : -(CH 2) 7-CH 3 or -(CH 2) 9-CH 3; G : sugar radical having 5 or 6 carbon atoms, preferably glucose unit; and p : 1-10, preferably 1.55-1.65. Independent claims are included for: (1) a washing or cleaning agent comprising at least one anionic surfactant, and 10-90 wt.% of at least one nonionic surfactant; and (2) use of nonionic surfactants to increase the washing power of greasy soils at temperature of less than 40[deg] C.
